MITER-BOX.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application led September 1, 1916;` Serial No. 118,026.

This invention relates to improvementsy in miter boxes.

The main objects of this invention are:

First, to provide an improv'edmiter box which may be quickly knocked down and compactly arranged for transportation, or quickly, set up or assembled.

Second, to provide an improved miter box which may be mounted on a vsaw horse or other support, such support constituting the bed piece of the boX.

Further objects, and objects relating to structural details, will denitely appear from the detailed descriptionto follow.

I accomplish the objects of my invention by the devices and means described in they following specification. The invention is clearly dened and pointed out in the claim v A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail perspective of a miter boX embodying the features of my invention with parts shown by dotted lines in order toy better illustrate their relation.l

Fig. II is an inverted planv View of the saw guide bar of my improved miterbox.

Fig. III is al detail longitudinal section on a line correspondingto line 3-3 of Figs. II and IV, show-ing the arrangement ofthe stoppin and the saw guide posts on the bar.

Fig. IV is a detail transverse section on a line corresponding to lines-4 of'Figs. II and III, showingY Vthey arrangement o-f the saw guide posts and means for detachably securing them.

Fig. V is an enlarged detail'section on a line corresponding to line 5-5 of Fig; II,

showing the mounting-of the saw guide bar upon its pivot.

Fig. VI is an enlarged. detail perspective of one of the saw guide posts, showing its mounting upon the saw guide bar.

Fig. VII is a plan view showing means for detachably securing the cross pieceto the saw guide. posts.V

Fig. VIII is an enlarged detail vertical section on a line corresponding to line 8-8 of Fig. I, showing details of the back member supports.

Fig. IX is an enlarged detail section on a line corresponding tov the line 9-9 of Fig. II.

In the drawing similar reference Characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the base 1 is provided with a quadrant 2 at the front thereof and has a number of vertically pro j ecting spaced back supports at the rear side thereof. The base is lighted by forming holestherein. The back supports 3 have vertical grooves 5 in their rear sides adapted to receivethe support members 6 of the detachable back members 7. These support members 6 are in the form of spring straps arranged over the back members which are preferably formed of wood, the front ends of the straps being countersunk or seated in grooves so that they are flush with the faces,

of the back members. The screws 8 are arranged through the arms of the supports and the back members as shown in Fig. VIII.

The miter boX is provided with legs 9 so that. it may rest on a bench or other support and is also adapted to be supported on a saw horse or other supporting bar 11, as illustrated in Fig. I. When so mounted on a saw horse or other supporting bar the support member constitutes the bed piece of the miter box. -The support member 11 is arranged on the base in front of the back member 7 and is clamped against the back members and to the base by means of the clamping screw 10 arranged through an upwardly projecting lug 10 on the base, as shown in Fig. I. With the parts thus arranged the clamping screw not only serves to secure-themiterboX to the support but also serves to clampthe back members rigidly in position.

On the Vunder side of the base I mount a saw guidebar 12 by means of the pivot 13, the` pivot' being arranged through the base 1 as shown in Fig. V. The saw guide bar 12 is detachably secured to the pivot 13 by meansofthe locking slide or plate l5 slotted to engage the notches 111 in the pivot, the

notches being below the bar so that when the locking plate is moved longitudinally yof the bar it 1s brought into and out of engagement therewith.

5 The slide or lock plate 15 is secured in its` adjusted positions by means of the thumb screw 16 engaging the slot 16 in the lock plate. By this arrangement the saw guide bar can be readily removed and replaced as occasion requires. j

The saw guide posts 18 are arranged in holes or sockets formed in bosses 17 at the ends of the saw guide bar. These posts are supported in the sockets by means of the pins 19 which engage notches 20 in the upper ends of the posts, the pins being extended to form linger pieces and constituting stop members coacting with the ends of the notches 20 to limit the rotative m0ve- 20 mentof the posts in their sockets.

The posts 18 are provided with notches 20 below the saw guide bar adapted to receive a spring catch 21 secured on the under side of 4the bar. The catches form retaining 25 means or locks preventing the Withdrawal of the posts when adjusted to locked position. When the posts are rotated however to withdrawing position the locking springs are disengaged from the notches and the posts may be drawn from; their sockets. The ends of the posts are beveled at 22 on the sides of their notches 20 so that they may be engaged with the spring catches by merely pushing them into their sockets while in locking position.

\ IOn' their upper ends the rods are provided with cross bar engaging lugs 23 in the form of headed studs or extensions adapted to engage the slots 26 in the end pieces 25 of the 40 cross or top bar 27. The lugs 23 are so positioned on the posts that when the postsl are in their unlocked position the lugs are alined with the slots 26 thereby permitting the placing or removal of the cross bar, the cross bar being locked when the posts are adjusted to locking position. The saw guide rollers 28 are mounted on the posts for vertical rotative movement thereon. These rollers are provided with rubber acings 29 and are held together by the cross pieces 31 which engage grooves in the upper ends thereof'. The saw 30, which is shown conventionally, is adapted to slip between these guide rollers which move up and down on the posts with thesaw.

A spring clasp saw support 32 is mounted on the top piece 27 for supporting the saw in an elevated position. The saw guides' normally rest on the supports 33 or' the posts.

The saw guide bar is held in its adjusted positionby means of lthe catch pin 35 which is supported by an arm 34 at the front of the quadrant 2, the quadrant being provided n with a scale indicia and corresponding holes 36 for the pin.

With the parts thus arranged this improved miter box may be very quickly assembled and disassembled and when assem# bled may be compactly arranged for storage or transportation. It can be mounted upon a saw horse which renders it of great convenience for use of carpenters and the like.

Thesaw horse or support, as stated, constitutes the bed piece of the box.

I have illustrated and described my improvements in an embodiment which I nd very satisfactory.
